In his first-ever interview, the sole Australian survivor of the Waco siege has revealed to 60 Minutes what really took place during the 51-day stand-off, and why he believes crazed cult leader David Koresh will one day return to Earth as the son of God.

Clavell's ex denies causing SA road death

The ex-girlfriend of dead fugitive Rodney Clavell has been ordered to stand trial over the hit-and-run death of a cyclist who was a leading Adelaide midwife.

Samantha Magdaleine Farrer, 37, of Queensland, pleaded not guilty on Friday to three charges in the Adelaide Magistrates Court, just around the corner from where her former boyfriend shot himself dead in a brothel after a 13-hour siege on Thursday.

She denied causing the death of Kathleen Heraghty, 48, by dangerous driving in December at Inman Valley Road, near Victor Harbor.

Farrer also pleaded not guilty to an aggravated count of driving without due care and to failing to stop at the scene of a fatal accident.

Mr Heraghty's obstetrician husband was cycling several minutes behind her and was one of the first people on the scene.

Farrer was ordered to stand trial in the District Court and the matter was adjourned to July 7.

Clavell accompanied her to an earlier court appearance in March, months before he became South Australia's most wanted man.
